BOX-\TAILING MACHINE.

Application filed July 31, 1917.

To all whom it may concern:

Be it known that 1, WILLIAM F. HARRIETT, a citizen of the United States, residing at 113 St. Nicholas avenue, in the city of New York, borough of Brooklyn, county of Kings, State of New York, have inventedcertain new and useful improvements in Box-Nailing Machines, of which the following is a specification.

My invention relates to box-nailing machines. More particularly it relates to an arrangement of parts whereby a chuck and the driver associated therewith may be removed from the machine without interferonce or disturbance of any or all of the other chucks carried by the carriage or other support and without removal of any part other than the chuck and driver. I will describe a box-nailing machine embodying my invention and then point out the novel features in the claims.

In the accompanying drawings Figure 1 is a front view of so much of a box-nailing machine as is necessary to illustrate my invention.

Fig. 2 is a vertical sectional View of Fig. 1 showing a chuck'and driver in position and also showing a second chuck and driver which is about to be removed. 7

Fig. 3 is a detail perspective view of a driver head plate embodied in my invention, and

Fig. 4 is a top plan view of Fig. 2 showing the position of the chuck and driver relatively to the driver head plate when the chuck and driver is in position to be removed.

Similar letters of reference designate corresponding parts in all of the figures.

A box nailing-machine for which my invention is adapted comprises, as is usual, a supporting table A (indicated in outline), a carriage B (partially illustrated) forming part of the frame-work of the machine, and a cross-head C which has a reciprocating movement in order that the drivers associated with the chucks may drive nails or other fastening devices into the box or boards supported by the table. These parts and their relative arrangement are all well understood by any one familiar with machines of this type or class.

D designates a chuck, several being shown in the drawings, which may be of any desired construction. Its function is to sue- Specification of Letters Patent. Patented July 9, 1918.

cessively receive through an opening d, and position for driving, nails or other fastening devices. Each chuck as here shown is mounted upon a pair of bars or supports d, and held in place thereon by means of a screw-threaded bolt (Z which passes through a washer 623 and enters a screw-threaded opening in the part (Z of the chuck, which as shown fits between the bars d. Flanges (Z also carried by the chucks engage with the bars 01 to assist in holding the chucks in position on the bars. The bars cl are attached at their ends to plates d, which slide in the carriage B. Handles (Z (only one of which isshown) are attached to each pair of plates for moving them back and forth. The handles (Z have screw-threaded ends which work inthe plates and pass through elongated openings or slots in the carriage. When the plates (Z are moved by the handles cl, to position the chucks, the plates are clamped in position by turning the handles (Z against the carriage. This adjustment of the chucks is well known, and is for the purpose of moving one set of chucks in advance of the other set so that the nails or other fastening devices may be staggered in the boX or boards.

Associated with each chuck D is a driver E, which is reciproeated by the cross-head C. The drivers are supported in the crosshead by means which, upon a relative movement of a chuck or said means, permit of a driver being withdrawn from the cross-head without the removal of said means or any part thereof. As here shown these means are in the form of plates 6, the plates being supported on flanges 0 of the cross-head. Each plate 6 is provided with a slot 6 terminating at one end in an opening 6 of a diameter equal to or larger than the diameter of the driver head, so that the driver may be disengaged from the plate by simply moving the driver along the slot until the opening is reached. The slotted end of the plate is toward the front of the machine and is of sufficient length to support the driver in any of its operative adjusted positions of its associated chuck.

In Fig. 2 the chuck D and driver E at the left of the figure is shown in operating position in the machine, While the other chuck and driver is shown in a position where it can be removed, and this is accomplished by merely unscrewing the bolt (Z and moving the chuck and driver to the rear of the machine until the driver-head is in line With the openinge of the plate, after "Which the chuck and driver may be removedfrom the machine. The driver is replaced in the plate e by insertion through the opening 0 and a forward movement in the slot.

What I claim as my invention is; V

1. In a box-nailing machine, in combination, a reciprocating cross-head; a carriage; a plurality of chucks carried thereby and each independently removable therefrom Without disturbing the other chucks; a plurality of drivers, one for each chuck, reciprocated' by the cross-head; and slotted plates carried by the cross-head for supporting the drivers in the cross-head, and permitting of the independent detachment of a driver from the cross-head, Without disturbingth'c other drivers.

2. In a box-nailing machine,'in combination, a carriage; a plurality of chucks carried thereby and each independently removable therefrom 'Without disturbing the other chucks; a reciprocating cross-head; a'plurality of drivers, one for each chuck, re ciprocated by the cross-head; and means drivers andradapted, by relative movement between said means and a driver, to permit the driver to be detached therefrom Without disturbing the other drivers.

3. In a box-nailing machine, incombination, a'carriage; a plurality of chucks -carried thereby and each independently removable therefroin Without disturbing the other chucks, a reciprocating cross-head; a plurality of drivers, one for each chuck, re-

ciprocated by the cross-head; and plates carried by the cross-head, one for each chuck, and each plate provided With a slot terminating at one end in an opening through which the head of its driver may pass, whereby the driver may be detached from the cross-head Without'disturbing the other drivers. 7 7

In testimony whereof I have hereunto signed my name in the'presence of tWo subscribing Witnesses.
